If I have somewhat similar content on a few pages does my meta tags have to be UNIQUE on each page OR is it okay to use the same meta tags and meta descriptions on Those pages ..
Can you remove the caps lock from your keyboard and bury it in your backyard? Every one of your post titles is annoying as hell.
Yeah meta descriptions aren't going to do a thing for your rankings but they'll help your CTR, so they can influence your traffic. BTW if Google doesn't think your meta desc is relevant to a search query they'll just take excerpts from your content and display that instead.
